Some of you may recall my RB20 powered 48 Studebaker, which I described here in some detail, and my RB20 powered RX-7. Both of these cars are running and driving very well. My Stiletto three wheeler was also running well until one day I had a wiring meltdown, cause unknown, that included melting the plastic box with all the relays and fuses. This is a 1984 Kawasaki Z1300 , one of the very first motorcycle engines with electronic fuel injection, and NOTHING was tuneable or adjustable except the idle speed. We discussed some of the aftermarket fuel injection systems. But we kept coming back to the fact that we had accumulated a lot of RB20 spare parts – ECU, ignition module, cam sensor, throttle sensor, MAF and a wire harness. The Kawasaki is a straight six, twin cams, same firing order – why not make it a research project ? The Kawasaki had a crank sensor only, with a lost spark system meaning it fired the plugs every revolution. My machinist made an adapter to drive the RB20 cam sensor off the exhaust cam, and the rest was pretty straight forward, not to say it was simple. I am using a Z32 instrument cluster - figuring out how to drive the electronic speedo may be a challenge. We built a custom intake plenum, used the RB20 injectors, coil packs, throttle body and TPS from an Infiniti J30 (Nissan Leopard), stock Kawasaki fuel pump (36 psi) and a custom made fuel rail, air box and air filter setup. We sent the ECU to ConceptZ to get the Nistune board installed, and my tuner guy wasted about a hour to figure out they had installed the wrong map. Once he downloaded the correct map he had it starting, idling and running smoothly in just a few minutes. We got a Code 21 fault, and I checked the coils – they all have the same primary resistance, and I don't know what else to check. It seems to run just fine. Any suggestions what else to check? The Youtube video shows the Stiletto running and driving with the original Kawasaki system – drove it for about 5 years with very few problems. http://stilettoman.info/2014/09/the-stiletto-project/
